CX4 Disable Mirrorview?

I have a CX4 array which we got used and came with Mirrorview enabled. It's allocated 2 of the front-end FC ports. I would like to get those ports back for front-end FC traffic to the hosts on the fabirc. We have other CX3/4 arrays and all 4 front-end ports are allocated to host traffic.

Is it possible to reconfigure the ports to be normal front-end ports, or is it possible to disable mirrorview in order to reclaim these ports?

Also, if im mis-understanding the configuration or usage of these ports, please let me know that as well.

Thanks,

Ron
